I am looking to pick up a preston frame and split between a Med and Lg. I about 6'2' but kinda like a smaller frame. I would like to have the smaller seat tube cause I would say my upper body is a little longer, for freeride. However this will be a all mountain bike and don't want to be cramp on XC rides. Right now I would say I am about 55/45% xc/fr. Is anyone my size riding a Med? Any help would be appreciated.
